Hey, I'm sure you are aware, but in case not or others are experiencing the same: I have found an issue with warehousing in this new patch using a completely fresh mod free city, while also using the --noWorkshop in the properties panel of the steam library.

First: Thanks for fixing the mass influx of goods when you place a new warehouse. This had a janky fix before, but your fix makes things easier and prevents the waves of trucks trying to top off a warehouse.

I did not do thorough testing. Only minimal from general zoned industry, and forestry industry.
It did not matter if it was general zoned goods, raw resource, or processed industry goods they have this same issues:

- Warehouses set to empty will rarely allow the incoming goods to reach its location, the trucks will instead find a new place to go. If the truck with the goods arrives it will sit in the street for a minute or so trying to drop off the goods, failing repeatedly, then deciding to export itself. I found on an even rarer occasion the warehouse will accept the goods.

- Warehouses set to empty will fail at receiving public services. You can watch the route being created to then disappear when the vehicles get too close, if you click on this vehicle it has decided to help someone else instead.

- Warehouses set to balanced can accept, export, and supply your city. As well as receive public services.

- Warehouses set to balanced seem to be hit or miss if it will work as expected. In one test city they would fill to 100% and do nothing, in another they worked like expected.

- Warehouses set to fill are capable of accepting city services and deliveries, however, they are incapable of sending goods anywhere in the city.

It appears that the largest warehouse has the highest chances of accepting goods.

I did not have to time to fully test this in every aspect, such as medium warehouses, but those are the general points I have gathered.

Can you replicate the issue? If yes, please explain how you did it.
Yes, I just place them down, set them to different settings, and watch them.

The Transfer Manager CE creator Sleepy also reports the H&T free update changed warehouse AI behavior. This needs to be hotfixed.

Messed around a little bit more today:
- Warehouses set to fill have a chance at working as intended.

Hi everyone,

I have found 3 bugs in WarehouseAI since the new patch:

1. WarehouseAI.RemoveGuestVehicles

Is treating m_transferType as a bitmask rather than an enum so it removes police cars and hearses and all sorts of stuff as well as the cargo trucks depending on the material stored in the warehouse.

2. In WarehouseAI.ProduceGoods

if ((buildingData.m_flags & Building.Flags.Downgrading) != 0)
{
RemoveGuestVehicles(buildingID, ref buildingData, actualTransferReason);
}

This bit of code in WarehouseAI.ProduceGoods stops "Empty" mode warehouses from ever receiving any requested material at all and due to the bug in WarehouseAI.RemoveGuestVehicles also stops warehouses set to "Empty" from receiving service vehicles as well depending on what material is being stored

3. The IN amount is now checking OUT truck counts (erroneously) and is restricted to a max value of 1, so your warehouses will quite often randomly not fill as they don't ask for material depending on how many trucks are out delivering.

I have patched these WarehouseAI bugs in Transfer Manager CE so in the short term if you can run mods then I highly recommend running it till these are fixed.

I only played an old save briefly after the patch (and the new save is still on pause) so I didn't notice this, but this sounds really worrying.

Thank you for the report. We're currently investigating the reported issues regarding warehouses.

Thank you for the report. We're currently investigating the reported issues regarding warehouses.

The issue also seems to affect the garbage collection process. Trucks only seem to go to Pedestrian service areas ,ignore large areas, return with low percentage to facility. 2-4 percent, hesitate in middle of the road.

What does this have to do with issues regarding warehouses? Garbage collection is a different issue.
